I love the exotically named Aruba range from Milano. It’s a really simple design, but I’d have it right up there as one of the most stylish modern radiator collections we offer. I have my eye on the dark blue horizontal model as and when the often dreaded and invariably inevitable call to “do up the house” comes.

I have common ground with a great many others in taking a fancy to the world’s favourite colour, blue, and it seems a half decent match with the radiator personality test. I’m generally very laid back on the rare occasions my little girl allows me to be, so tranquil and calm connotations would appear to fit well.

I was delighted to be told I’d made it into the top 5 most read authors on the subject of radiators and designer radiators in 2021, landing in 4th place on the list. It’s a labour of love, but great to know so many people have enjoyed (or at the very least tolerated) my radiator ramblings over such an extensive period.
